Since joining TwitterRobert Downey Jr. has been feeding his fans innocuous photos from the production of Avengers: The Age of Ultron. But they are pretty cool in that they give us a glimpse into the dynamic of the cast and crew. Take this photo of the cast and crew at brunch. Other than the actors and director Joss Whedon, a lot of the faces are unfamiliar but no less important.

Movie sets and productions have an interesting energy about them. From the low paid grunt to the a-list actor, everyone recognizes that what they are doing is rare and special. There are more successful politicians than there are successful actors, directors, and writers combined. It's amazing to think of all the specialized talent and effort that go into telling good stories.
